Pityriasis lichenoides et varioliformis acuta, commonly referred to as PLEVA, is an acute form of pityriasis lichenoides which manifests as crops of oedematous pink papules over the proximal limbs and trunk which progress to vesicles and central haemorrhagic necrosis before healing with scarring. The cause of PLEVA is unknown. It may be confused clinically with varicella.
